Am I nuts to replace the seals when I replace the timing belt?

Maintenance/Repairs

My 2008 Solara (3MZ-FE engine) just crossed 90k miles, so I am planning to replace the timing belt. I
am considering replacing the cam and crank seals, and maybe the oil pump
seal, as long as I have things apart. But a voice in my head says “if it ain’t
broke, don’t fix it.” I have not replaced shaft seals before, but have researched
the seal replacement thoroughly, am a decent backyard mechanic, and don’t
need the car back on the road immediately if I need to get assistance. My
question: should I leave well enough alone, or is this a manageable
proposition?
