Option one: modify DEFAULT_ROUTE_LEN and recompile.

Option two: use the control protocol to EXTENDCIRCUIT the two hops
you had in mind.

That said, please only do this as part of a research exercise:

Using two hops without entry guards will greatly reduce your anonymity:

and using entry guards with one extra hop will also be quite bad.
