ok - so you would leave the existing flange there, put laminate flooring in place around it, drop in the 7530 Fluidmaster Better Than Wax Toilet Seal (https://www.amazon.com/gp/product/B00R7D35TQ) and put toilet on top of that?
The standard kit for a silicone replacement ring has an extender for window. Flange is slightly below floor level. Buy the kit and take a look at it before you change the flange.

I will never use a wax ring after finding this.
