PS Allocations & Deductions in Control Group

Control group A & B has a PSP with individual allocation groups. I know that if AB files consolidated tax return that the 25% deduction limit is applied to eligible payroll for the CG, and if separate returns I believe the 25% is applied separately to each.

Assuming that, my question concerns the situation where the owner (both A & B are S-corps) gets a much smaller W2 from A than B but still gets maximum PS in total. There is an NHCE in A that requires a large contribution such that the total PS for A would exceed 25% of A's payroll if the owner's total PS% was applied to each of his W2s (equally pro-rated). My question is, can A say the owner's PS is 5% of pay while B determines the owner will get 40% of pay? That is, skewing the owner's PS toward the company with the higher payroll so that each company's deduction does not exceed 25%.

I think that is OK, but looking for additional expert opinions - thanks in advance.
