Looks illegal to me, with or without the chalk being used to 'level' the illegally used bridge.
I wonder if it would be ok to place two bridges(without chalk levelers) across the rails, next to each other, with the bridge heads on opposite rails, located such that the 'crotch' of the two bridge sticks could hold your cue shaft in a controllable spot, to shoot the shot.
Probably not though if using the WPA referenced rule, since the bridge(s) are not being used in the intended fashion(bridgehead assisting), but rather as a suspended support for your bridge hand.
If gambling....build an erector set with bridges, cue racks and mop handles, and cue holder clippy things that look like potato chip bag clamps and hope it doesn't all fall on more than one ball.
