There's really nothing in the rules about transferring after the school year starts.
There's a handful of exceptions and the "bona fide" change of address is the one that's the easiest to jam through.

A few years ago, Perry Central had two kids they were fighting with for eligibility.
Deandre Reed transferred from Georgia (from Cordia originally) and he had to sit out a year and started playing late in the season.
Marquis Frazier transferred from Cordia and he was ruled eligible officially by the KHSAA a couple days before his year was up (great work, KHSAA).

One kid transferred in via the foster care system midseason and was eligible immediately.
