If I traveled fast enough, my current understanding is that visible light would be blueshifted to the blue/UV range, but also that microwaves and longer wavelength waves would be blueshifted into the visible range. Is this true

If it was you your boring ass, you'd know.

The OP has right idea. Don't limit to small shifts. There are free electron lasers that upconvert microwave beams into ultraviolet light. And there are free electron laser type devices that that can downshiftbmicrowaves into the ALF & ULF Amanda (Super Low Freq and Ultra Low frequency, SLF = 30 to 300Hz... ULF = 300 to 3kHz

..your point 5:46?

Those FELs (free electron lasers) using free-space, traveling EM plane waves in place of the "wiggler" ...the plane wave "coherently-scatters" off the oncoming relativistic electron beam at energies between 2MeV to 15GeV. For example near IR ~1.06 micron lasee beams are upconverted to coherent beams of hard Xrays or even gamma rays !

Get on your bicycle and ride down a big hill and find out.
