PMS or AST top mounts

[MLB]

Currently have standard shocks and lowering springs with PMS top mounts and brace.

These have been drilled in.

Is it a problem to remove the PMS items and fit AST top mounts for more caster when fitting AST coilovers, leaving the holes?

Or caster not worth it and just keep the PMS top mounts with AST coilovers?
