I would rather convert the printer to direct drive first. There are various variations which are not expensive. I went with a cheap BMG extruder clone.

You can print TPU using a Bowden setup, though you will have to slow your print down speed and tweak with your retraction settings too. 95A should work, softer TPU may work though I can't really guarantee that
It's easier to print flexibles with a direct drive setup. There are some printable direct drive mods for the ender 3 which others have had success with, may be something to look into!
It's tricky but not impossible, I've done it with my Ender 3. You do need a different extruded though as the stock one has too large of a gap and the filament can easily kink and escape it. Clone BMG is a good choice, but you can also print a version of the stock one with tighter filament path. If you aren't going to print flexibles more, you can keep it bowden - adding the mass of a DD brings its own problems. After that it's just a matter of very slow primt speed (like 15mm/s slow) and little to no retraction using 95 TPU.
