The F4i shock, while cheap and abundant on the market, is much shorter and the spring rate much lighter than the superhawk. I "pioneered" this mod on the vtec vfr and it works well for light riders. It may fair better on the VTR with its lighter weight tho' but it will need a substantial upper extension.
Also, because of the VTR's dual exhaust it might be difficult to reach the rebound adjuster screw on the bottom. Again, pic is from a VFR with a right side only exhaust.
On superbling, I successfully ran a penske cbr954 shock because it was valved/sprung for a heavy 954 rider (210+ lbs) since stock is also lighter than the 'hawk. No closeup handy but you can see the reservoir in this shot.
At 345mm, the VTR shock is about the longest modern honda shock made. The VFR and cbr1100xx are the next closest in size and spring rate. Unfortunately, these aren't upgrades either (rebound only, no reservoir, etc). FWIW: On superbling I also experimented with a very tired fox cbr900rr, a ducati 916, R6, R1, an ohlins VTR unit in dire need of a rebuild and of all those the worn out ohlins was still the best.
R1 shock with custom spring sure looked purty tho'!
HTH

how hard is it to fit a vfr tank? i need a new tank anyways and it seems like vfr tanks are more common and cheaper

As posted in our classifieds, here's a VFR unit that will with minor modding (adding a spacer to get the correct length):
