Yup, if you want 4-pots IMO it makes sense to have the forks to make use of them, since the standard forks are overwhelmed by the stock calipers. I reckon sorted forks with standard brakes would stop you faster than standard forks with stronger brakes, myself.
SRAD 600 would be a RWU fork with fairly easy fitment and 4-pot calipers by the way, a la TSM. It doesn't fit your yokes but the SRAD yokes are a good fit for the SV. Or, other GSXR USD forks work too.
It sounds really intimidating and expensive, but it's actually not, if you can bleed brakes and change a bearing you can fit a GSXR front end... And if your SV parts are in good nick you should get a good return on those, my SV parts would have paid for the GSXR parts I used if I'd not got carried away. depending on your weight and teh forks, paying for a service and rebuild is often wise too, I got away with it as I got good forks and I'm very light. I probably shouldn't say all this as the GSXR fronts really seem to impress people
