Thinner Rega Felt Mat for 180-200g Vinyl?

Does anyone know of a thinner felt mat similar to the stock Rega mat that I could use for thicker 180g and 200g pressings so the VTA ends up being about right?

I'm using a stock Rega P5 with the Rega Exact cartridge.

I appreciate any input but don't want to get into a discussion on non-felt mats. I've tried several and am happiest with the Rega felt mats - just looking for something not quite as thick for use with the thicker vinyl records.
I was able to get a Linn Felt mat for thicker records from a Linn dealer.Good quality mat but expensive.I do use D.J mats as well of acrylic material and they are quite neutral and seem o.k as well.
