well, maybe for an FXO (I don't know because I don't drive that car) it does make sense, but not for XRT. XRT has a a great tyre wear, and tyres don't heat up to much and do it equally, with a proper setup, if you have troubles with fronts of XRT you might be using too much steering input (XRT rarely needs it, mostly steered with the throttle) or using too much camber with too soft pressures.
I took part in GTTC cup with XRT, races were about 30 mins long and I had no problems with tyres, they heated equally and not higher than 74-78 *C.
Here are some of the sets I used, they were based on HL sets, with tweaked camber/pressures.
