12 valve swap drive by wire pedal

I’m looking at converting one of these trucks to a 12 valve. I had an 03 with a 12V that used the apps like a 24v. The later trucks 04.5 and up I believe were drive by wire. Could you put the older pedal assembly in? I like to retain cruise also. Thanks in advance!

I'd like to know also, got a 06 that will prolly get a 12 valve.
