how insane would adding 2 hobby rockets to a trainer be?
"I know nothing.... I see nothing!"
I think if someone was to come out to a desert with something like what he is thinking, there is plenty of room, etc to fly out a reasonable distance and light the engines and feel reasonably safe about your "test flight". Sure, it'll probably burn the plane up as it crashes at mach 1 into the ground. That's half the fun of this type of thing.
I guess I'm assuming you are at an age where the whole "don't try it around people" thing would be obvious. I shouldn't assume. So, just don't do it where it would have any chance to hit someone.

PS- I found the pic on the 'net a while ago. It is a very popular pic among the Jet guys. And, no, the AMA would not condone such activity. Find a desert. Lots of those in Littleton! HA!
