Not sure what you mean by "almost different".  Slightly different?

It is possible.   It would have to be done at a fairly low level in the
stack.  My gut feeling is you'd be biting
off a lot.  Asking for lots of problems.

What problem are you trying to solve?  In other words what are you trying to
do with the node that
is communicating using the T1 stack?

A different approach would be to build a T1-T2 gateway.  A node that has two
radios or possibly one radio
attached to two stacks.  But this too seems like more trouble then it is
worth.
