Hi Rome,
I have done most of this in pieces, on multiple bikes.
The SRv2 will accept 700c wheels very nicely. You will need a set of road calipers to install on the front fork and the rear swing arm, on the brake bridge provided.
The cassette change is straightforward; I am using an SRAM 11-34 9-speed cassette on my SRv1 prototype. You will need to change the right shifter to a 9-speed Shimano-compatible shifter. The freehub body will accept anything that's Shimano-compatible.
What other questions do you have?
Best,
Doug
