Replying to s912 ps bindings -mount without lifter?

can salomon s912 ps bindings be mounted without the lifter... they look exactly like TI's so, it seems like it could be done, but it looks like TI's might have their own heel piece... would a shop be able to set up the PS like the TI's?

i got my sister these bindings and some v-expressions for xmas, and i want to get them mounted soon. would have just got TI's, but i got these for $100 brand new.
