I do not anticipate that multiple Tbolts would interact in a negative 
manner if they were connected to a good linear supply capable of driving 
them all.  Of course, there is always a possibility that I'm wrong and 
they would interact.  Only trying it will answer that question.

Note that, as Bob pointed out, the +12v supply will need to source 
700-800mA *per Tbolt* for a few minutes if they are all powered up at 
once from cold.  Even if you wouldn't do this in a manual startup, it 
would happen when the power came back on if you had a power failure 
(unless you devised some automatic means to prevent it).

Best regards,
