tm2 v2 - flipping the rear wishbones/shocks and bleeding the shocks

[vrooom]

Can I flip the rear wishbone backward with rear shocks mounted on the back of shock tower without big changes to handling?

Also how do you bleed the bleeder style shocks? Am I doing it right by
1) fill it to brim on shock body,
2) move the shaft to let the bubbles out
3) fill the oil on cap
4) screw it together,
5) remove the bleeder screw
6) let the oil come out. (how much oil should come out?)
7) put the bleeder screw back in.
