Anyone tried one of the Hyperion TX packs in a DX3R?

Having a look on the Hyperion website I found these HP-FG305-2080-2S http://media.hyperion.hk/dn/fg3radio/. Looks like if might fit in the 3r with a few mods.

HP-FG305-2080-2S is a replacement for CAR Tx (or any) which use 5-cell NiMH "flat" packs, such as Futaba 4PK Pistol grip Tx.

* Absolute Max charge rate is 4.8A, as this is the rating of the PCM safety chips used inside the packs. Still this is quite a high charge rate, and allows recharge in 30-45 minutes, typically.
* The PCM device protects the pack from over-voltage charging. It also allows the pack to remain installed in the transmitter, and then be charged with the standard NiCd or NiMH wall-charger which comes with most transmitters.
(wall chargers up to 12V max for 3S packs, or 8V for 2S are usable)
