If you must have front wheel drive, you can always fit a towhook to the front for recoiver (on a temporay basis), Buy a second towing eye and weld a tow ball to it. Screw it into the front towing point for temporary boat towing (going backwards, of course).

Great minds etc....
A few years ago, I was inspired by a front hitch we had fitted to a Hilux at work (the "receiver" socket could also be used as a winch mount, vice mount, hose reel carrier etc. Bit of a poor mans Unimog!) to try something similar to your idea wth with my golf.
https://www.watling-towbars.co.uk/launching_boats.htmlI feel they are reasonably priced? However, not at all suitable for a gti! And Fitting to a modern, leased SUV is extortionate (too much fancy bodywork)...then you need to pay again to take it off and make good at lease end.
Golf. I used a thread tow hitch, dropped thru the tow eye (no welding necessary) with penny washers etc from local tractor dealers. Not expensive. Forms one big bolted connection, no heat involved.
Problem. What with all the "aero" kit, on the gti, bigger bumpers maybe, I couldn't find an emergency towing/recovery stem eye, with a long enough neck to give me adequate clearance tow hitch/ bumper when manoeuvring. They contacted.
Extra long neck in itself potentially an issue too. Maybe too much leverage on design rating of chassis socket, for an off centre load? Unsure. My car eye was a LH thread so not easily "home-made". I gave up....
Method may work on other cars? Worth a try for £30ish?
You've reminded me to pull the bits out the back of the shed, and try the tiguan for size!
