wm 6.5 cannot be installed on HTC LEGEND or HTC DESIRE because windows mobile 6.5 need to be configured, run and reconise the insternal drivers in HTC LEGEND/HTC DESIRE which is very difficult to do.

no windows mobile roms are available for HTC LEGEND or HTC DESIRE

It's easy, I am running windows 7 mobile on my HTC desire, used squirky, just google it...
