Can I eliminate the wall wart that comes with my M1XEP by sniping off the transforme, then connect the wires from the M1XEP to one of the 12VDC outputs on the ELK M1 panel?
Can M1XEP connect to 12VDC outputs on M1?

Yes, you just have to make sure to connect the polarity correctly.
I do this all the time, assuming proper power provisions from the panel or aux supply. Also allows the power to be run through an output to allow a "remote reset" if ever needed. I've had a couple of accounts with VPN's that for whatever reason the XEP's would remain on the network, pingable, however RP would not connect, even after rebooting the machine.

If you are doing the remote reset because the M1XEP is misbehaving, do you initiate the reset by dial-in?

Thanks for the responses Kazibole & Work2Play.
My only plans are to connect the M1XEP there and perhaps the door bell module. I have a 12V powersupply elsewhere that replaces all my other wall warts! I would assume those 2 things are within specs.

You can still do this using the wallwart. Just cut the hot side of the wire from the wall wart to the xep and run it through a relay. Similarly you can run your modem and router through relays.
I would think most people would have ups for the modems and switches. Heck I put the largest ups I can on my modem, switch and wireless AP. why because when we lose power those stay alive on ups for almost 4 hours which things like the iPad and iPhones can continue to have network.
Dial in is always an option, provided the system is connected to a POTS line or equivalent, however I have had minor difficulties on digital lines (glorified VOIP).
In the cases I've had to do this, the client had enterprise grade IP hardware for the network, however I didn't admin the network, so if that hardware went down or needed a reset, I honestly, didn't really care, but if it saved a drive for me to do a power cycle on my hardware, I'd take it.
We do have some hardware connected to smart UPS' which we do admin remotely and do exactly just that, cycle power and reset remotely, however if the ISP or network is down, not much you can do then.
The particular install design criteria for the install dictates if we can get rid of a lot of wall warts or not, but if we're considering a supply to simply negate a wart or two, it's not worth it a lot of times.

Related but different.
I have found on more than one occasion that flaky routers and modems are not flaky, but rather get crappy power. I have replaced my wall warts with an ATX power supply at work and the office and have now gone many months without a single reboot required. This compares to every few weeks needing a reboot before that. And prior to that, I have had modems get flaky and putting a new wall wart fixed it.. . . at least for a while. I really think crappy power causes most of the headaches associated with a lot of these devices.
Interesting. Perhaps. I guess it never occurred to me. I have the computer on a UPS but the telco stuff is off in a stereo closet, and I just never bothered. Maybe most people do. Maybe its from having a laptop around.
At one point I had a 1500 smart-UPS sitting in my closet powering the network gear and my server. I then wired up an inlet to (2) 3-gang receptacles - 1 behind my desk and 1 behind my wife's desk to power our workstations.

I have my cable modem, router, and Vonage telephone adapter on a UPS. I would like to be able to access the M1 with RP to reset the cable modem and router, but if they work well enough to get me through to the M1XEP, then they don't need to be reset. I can't even dial in to the M1 if there is a problem since my Vonage adapter also requires a functioning modem and router.
Since I've had to reset less than once a year, I'll learn to live with it.
