I have an application were a supplier has several single phase loadcenter, these are exp proof units

they would like to use with incoming power 208 3 phase,

any suggestion on how to salvage the loadcenters

and still use the loadcenters

would a distribution block and use only 2 legs with the ground be allowable
 
as long as you have only 115V L-N loads, I don't see any problems.

if there are any loads that expect 230V L-L you may have a problem.

if there is just one load that is a problem, a simple transformer is all it takes to fix that one issue.

Basically, yes. Connect each panel to two legs and the neutral (if any of your loads are line-to-neutral), either A-B, B-C, C-A, etc., or A-B, C-A, B-C, etc.

A single large 3-phase distribution panel with 2-pole breakers will satisfy this, and maybe be better than just splicing them. Try for phase-load balancing.
