In a word, no. ELK and HAI use a proprietary signaling between the panel and touchscreen, so at the minimum you'd need to figure that out first. Then (not sure about ELK) but HAI panel touchscreens have many screens in firmware in the device itself. Other screens are downloaded from the panel. So if you were an EE and spent a year reverse engineering a touchscreen, you could potentially do this, but it would probably be better use of your time to spend the time getting a job, then use your first paycheck to buy a ELK or HAI touchscreen.
