Hi sixblades,
I’m afraid you can’t delay automatic reconnection attempts (if enabled) for when Viscosity connects local network drop outs and reconnections. You could try downloading the latest beta version and turning off the “Disable back to My Mac while connected (recommended)” option under Preferences->Advanced. This will likely stop Messages going briefly offline during a connect attempt, however BTMM is known to cause both DNS and IP assignment issues, so if you run into any problems you should turn the option back on.
The beta version can be downloaded from:
