Question regarding early baktrian FM Bodyguards

[Bava]

After reading some of the unit descriptions for Baktria for the 1832 time ( i just love them), i wonder if the new FM bodyguards (hetairoi kataphraktoi) are going to replace the old ones completly or if they´ll still be available for recruiting in MICs after some sort of reform?

Quote unit description text (bolded for relevance)

Even if the much heavier Hetairoi Kataphraktoi superceded them in guarding the Kingdom's Royalty, their position in the battle line remained unchallenged as they were much more mobile and could easily retreat and regroup than Kataphracts. They fought in the Heavier cavalry flanks guarding them from more agile opponents, much like hypaspists and thureophoroi guarded the pike armed phalanxes in the infantry.

It would a shame to loose these guys, as they are some of the best looking units i´ve ever seen in a RTW mod.
