So, I have finally found a topic about which audiophiles have no opinions? Wow!

Although this appears to be discontinued, it appears to be exactly what you need so maybe try to track one down or something similar.
Other options (although more complex) would be a recording mixer that has assignable I/O routing.
That said, of your options above:
1 - Could be OK, but can't imagine that the quality of the RS box is very good plus it only has a single output so night ideally suited.
2 - Aside from Y cables, this looks like a better solution than #1
3 - Nope - Wouldn't add any active device in the signal chain as it will effect the sound and has its own gain section.
4 - I like this option best, but not knowing your gear, I assume that there's no way to bypass the gain stage on TP1 before routing to TP2, so that will require fiddling for every recording session.
Personally, if it were me I would:
1- Try to track down a similar unit to the one that I linked to
2- Pursue a proper professional recording mixer/ console that would have assignable I/O's and loops for your EQ
3- Consider getting a different EQ (cheap) that has TP1/TP2 switching
Good luck with this one
