Options for removing strut towers?

So I have a 86 mustang that is back halfed. This off season I want to bring the cage out into the engine bay and also modify or remove strut towers to gain access to spark plugs and help with header removal.
I don't want to convert to mustang 2 front, and rather not do a full front chasis.
I already have the top and one side of factory frame rail plated over.
So what's sum options? I'd like to remove strut tower completely

We just drill strategic holes in the strut towers for plug removal.
