Resize tab staff independent of regular?

I’d like to make the tab staff larger without increasing the size of the 5-line staff.

The reason is that the tab numbers were colliding at a larger point size, but now they’re too small for older eyes. Or is there a way to increase the space between tab lines?

You’ll need to use two players, one showing notation and the other showing tablature, so that you can apply a custom player scale factor to one of the two players.
