The only way you could attempt to shorten the lever stroke in these brakes it to highly pressurise the system. Close the bleed port at the lever and forcefully inject fluid at the caliper. The inward pressure will force the pistons out a little bit closer to the rotor."

You can't pressurize the system. You can
- get all the air out
- use a smaller bleed block
Which has the same effect as pushing in more fluid with the normal sized bleed block.

use a smaller bleed block

This was the solution I was going for. I even found a guy selling custom printed bleed blocks that were, say, 1% smaller than stock Shimano ones for just this problem.

If people are making custom parts for an issue, you can be pretty sure it's not a mechanic's problem.
