Advice on heavy laden kickstand options please (UK)

Looking for UK recommendations or alternatives to kickstands (or EU/USA that aren't mega expensive to import).

I have a twin leg stand that has warped and can't take the weight anymore. Regularly commuting towing a kids bike on a Follow Me Tandem. But most weight comes from panniers loaded for touring.

Running a Specialized Tricross Sport triple circa 2010, that's been Frankenstein'ed over the years with new brakes, ergo grips and front and rear racks.

Gap in front of rear wheel is very tight, so doubt I would go for that type of twin leg again.

I use a ball bungy already to steady the front wheel. Happy with that (although if I went Click-stand I'd probably chuck in some if his brake squeezers too)

Open to using two stands to spread the load e.g. Mini one off the front lower rack, one off the triangle. Would that work?

Open to Click-Stand type things but might find it faffy? Also tempted to DIY one from a tent pole first to try it out.

Keen to hear any ideas or suggestions please! Especially any alternative suppliers other than what I've found online recommended: Hebie, Click-Stand and Pletscher (which I doubt I could fit in the same gap in front of wheel.

*Boring background info last:

I've been using a hefty M-Part Primo Twin Leg Kickstand to support my commuting/touring set up for a few years. But it's always been a tad risky as the gap between rear wheel and the mount is scarily close, and it would occasionally move a bit and start to rub lightly, causing me to have to whip out the giant Allen key to adjust. I even had to file out a little hollow to give the wheel a bit more breathing space (totally risky set up I admit).

Now the mount has warped completely and I just can't get it to stay in place more than a few stops, even with little weight on the bike. Hence my search for something new!

Regularly commuting with my son in tow on a Follow Me Tandem. Panniers normally on back, but when touring may have both front and back.
