If you are late, as you said, you can adjust the FPA to recover to the "doughnut" which is the vertical guidance path indicator. Withing a few hundred feet you should be stabilized at the correct FPA.
I might be misunderstanding your post, but I hope you would ignore the "doughnut" on an NPA, with no GPS? It bears no relation to reality and just reflects where the aircraft "thinks" it is.
As Capn Bloggs says:
IMO, far better to set up the 3.08° further back and clip the FAF/2000ft on a steady descent path with minor FPA adjustments to go down the charted Altitude/Distance profile
