Does a wireless (tri-mode) custom TKL/75% with VIA/QMK exist?

I am trying to build a keyboard for my sister in law as she uses a crappy one at work. Her keyboard is tri-mode and she really likes that about it, as well as the shortcut keys on that board. With Software I could map any shortcut or macro she wants, so that is important for this build. Hot-swap might be asking for too much, but I know how to solder so it does not really matter (especially since she will never go as far as to even take a keycap off).

Does a TKL or 75% of these specs exist?

I've been looking but the boards I see aren't tri-mode and software compatible.
