I have half a mind to build a LEGO-compatible 9V battery holder just to try
some tiny vehicle designs. Without an RCX you can't make it do much, but it
would still be really fun to build small Technic models powered by a 9V battery
and a micromotor. With four small wheels, some gears and a polarity switch the
whole thing could still fit in a volume about 10 x 6 x 4 SLU's, which isn't
even as big as the RCX!
If you're worried about current you can always use one of those (expensive)
zinc air batteries:

(Mallory-Duracell has one too but I can't find info about it on the Web)
