Alas, I think that strictly by following the rules, the followup is a separate, but immediately following piece of a step of an Action than the pushback. First you fully resolve the chainpush and then you decide whether you follow it. Also, even during the pushback resolvation, the square the blockee occupied, is vacated immediately with the first push, so that square should technically be considered empty when chainpushing.
However, I have constructed a setup, where you push a player into the "inner ring" of the "accelerator" so that the pushes come around and the inner ring effectively has one player too much causing the push chain to continue as long as the active player chooses. This however requires 28 players on the pitch, and LRB6 gives you a maximum of 26 players on the pitch (22 + 1 extra from a card, the fanatic from card, Borg and the Other Machine).
In such setup you could push the ballcarrier a maximum of 4 squares by the one block you would make.
Is it ok to leave the setup as an excersise to the reader? You just have to add six players to the self-push-scenario, and the first two are trivial.

If somebody can achieve this with 26 players, I applaud them!
It is also possible to infinitely push oneself, if one can set up unlimited amounts of players on the pitch. Required number of players is somewhere around 30-40ish.
Thank you for the attention!
