I run 6800 brakes on several of my 10-speed bikes, they work reall well. The 6800 brakes are excellent brakes and are even better with Kool Stop salmon pads.

Which 105 is something you have failed to mention, as there were 2 generations 5600 and 5700 with 10 speed, and there was a change in the cable pull between them, if running 5700, no issues.

See C-456 on this document, https://www.google.com/url?sa=t&rct=...NmRYDOnfL2BxUW

Brifters = Brake + shifter, it's the shifter with the speeds index shifting count, , not the brakes ...

the wheel caliper criteria is Reach that being the distance between the mounting bolt hole and the wheel rim..

It's also the cable pull requirement. Newer Shimano calipers require a longer cable pull levers than earlier models. It's like the difference between cantilever and V-brakes but not as extreme. Using newer calipers with older short pull levers will require more lever travel to apply the brakes.

My wife has had 6800-series brakes with 6700-series levers for a couple years now. No problems.

Difference IMO not significant but to the OCD and you know who you are ...

TRP made 2 generations of mini V brakes 1 an 8.4 arm , the next a 9.0 cm long arm.. to be on top of that change by Shimano..

May philosophy is, if I already OWN parts, I'll bolt up almost anything and see if I can get it to work to my satisfaction. If I'm BUYING parts, I'll always hold out for stuff that's supposed to work together.

The issue here is cable pull. Too little is always a problem because your lever will bottom out against the handlebar. I've personally not found too much cable pull to be a problem for the kind of riding that I do today.

Look on the parts they should have a series # on them.5600 would be first gen 10 speed and 5700 second gen.
I believe shift cable out the side is 5600 and hidden 5700.

You can also check the compatibility charts.

I like the 6800 brake calipers and have used them with non-Shimano brakes levers for quite some time.

If the calipers take more cable pull than the levers, yes, the levers could bottom out, but it might also mean one needs tighter overall tolerances with wheel truing, brake clearances, brake adjustment, and quality of cables, housing, and cable stops.

As others mentioned, I'd try it out on a personal bike. If I didn't like it, then I'd make changes.
