Surprisingly, a recent paper found that such removal does indeed have an
apparent strong effect upon DWV replication:
Haemolymph removal by the parasite Varroa destructor can trigger the
proliferation of the Deformed Wing Virus in mite infested bees (Apis
mellifera), contributing to enhanced pathogen virulence.

Correct--so it's likely a safe assumption that digestion of the fat bodies
would have a profound adverse effect upon the bee.

This is a feeding method commonly employed by arachnids--such as splders.
And yes, after such extra-oral digestion, the mite would be expected to
then suck up a mixture of digested fat bodies AND some haemolymph.
