That's actually quite interesting idea, but I would probably make this as a new taunt while others would be able to join him, but it would probably have to be like: those players who join it, would not be available to do anything in case of going somewhere else, I mean like only the player who would start this taunt would choose the direction of marching and other would just join and march with him... That would be actually really cool. Maybe if there would be at least some option for those marching ones to say something interesting, because who would join such a taunt, where you can do just nothing except watching your character going somewhere being lead by someone else? (except me)

Basically I mean, it would be weird if there would be plenty of random-marching-around people around, that would completly broke the taunt, it just need to be organized.
(That would be probably the most organized thing in history of TF2)

Uff, I didn't meant it to make it so long, so sorry for wasting your time, but I wasn't able to shorten it more.
Anyway, good idea man!

Well actually that reminds me, that there is one more organized thing in TF2...
And that is Valve emptying your wallet.

I've made a taunt close to your idea https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1496794714
Except he doesn't say "left, right!" maybe Valve will add this if accpeted
