Dot and dab and noise, wonky wall

Hopefully the title tells the tale- half brick internal wall between bathroom & bedroom with a bit of a lean on it (+40 at rhe foot of the wall)
Using the @noseall method (solid top & bottom, solid verticals every 300).
Is there any gain to be had from chucking a load of cement render or browning or similar at the wall between the adhesive stripes to add mass & reduce the air gap (thus maybe reducing noise transfer from bathroom to bedroom)?

U might as well have the walls floated if you're gonna go to that extent.

Aye, was contemplating that option as well. Its a lime mortar internal wall, will cement render cause me any problems? (Denser so more mass so better noise reduction).
