One way to avoid pushing that NR rear too hard is to replace your very correct 52-47-36/14-28 w/ something like 48-44-36/13-28. Same range, 1.5 inches less chain windup required.
While there's certainly validity to your plan, there is still the issue of the 28t cog, as the NR is rated for a 26t max cog. While many claim they have exceeded 26t, it seems to be hit and miss. Best to check this on the OP's setup first.
