Do you mean turn a 256KB MSV11-PK into a 512KB MSV11-PL?

I have an M8067-LB in front of me right now that is fully stuffed with
8 rows of 9 MK4564N chips which should work out to be 512KB, which
matches the M8067-LA MSV11-PL description in the PDP-11 field guide.
The only way the memory could be doubled would be to replace the 64K
chips with half as many 256K chips.  Does the board support 256K
chips?
