43mm adapters?

I just had a crazy idea...did anyone ever try putting a 43mm tele adapter or wide angle adapter over some M Mount lens? I've just bought a nokton 35mm 1.4 and I was thinking how cool it would to be able to shoot with this lens for everything. Want wider? Slap a quality x0.5 wide angle adapter on it. Want tele? Slap a quality x3 tele converter on it.

Did anyone ever try this? Do you think it would degrade the IQ too much?
