With the bike on the centre stand you could prop bike under sump as suggested, then remove front wheel and brake caliper, loosen upper and lower yoke pinch bolts and slide fork legs out to give clearance for work. If you only need a few inches of clearance then maybe you don’t even need to remove the wheel, just remove brake caliper to allow forks to move downwards. Removing the handle bars and top yoke sort of seems messy to me, mostly because of the brake fluid in the reservoir as already mentioned. In my experience loose bars with everything attached are just sort of difficult to secure they seem to want to try to fall everywhere and scratch things. If you do go the top yoke way Get some hooks prepared to hold the bars up.
