This would be do-able, but it would probably require a modified Alltek board with more durable switches to choose the games. Those slide switches usually are not rated for constant use (for instance the ones we use at work are rated for 300 operations).
Many of the classic Stern backglasses are not protected by copyright, so they would be cheap to reproduce (or maybe make a combo backglass like Galga/Ms. Pacman has on the video games).
Catacomb obviously would be the hardest to repo because of the backglass game. Viper would be tougher too because of the turret. Otherwise, most of the games would be not too difficult once you had the playfield.
