Psionic Helm

I have worked out the following description for a Psionic Helm, please tell me what you think of it.

The Psionic Helm is a Spelljamming helm that converts psionic power into
motive force. It operates in much the same way as a standard magic-using
helm, and looks mostly the same. The psionic helm is usually a chair with
some sort of apparatus around the helmsmans head (such as a metal band, a
ring of floating gems, a helmet of some sort, etc.)

However, the psionic helms have a few special properties. A psionist may
channel powers through the helm to effect the ship, however not all powers
will apply to the ship, but may effect the crew. Powers such as Flesh Armor
will effect the hull strength, but powers such that effect ability scores
have an effect on the crew (it is up to the DM to determine what the power
will do.) Channeled powers require much power to operate, usually the
standard PSP cost plus 1 PSP per ship ton or member of crew, depending on
what the power effects.

The psionic helm uses a different cost base than standard helm. Costing 1
PSP per ship ton (ST) per moverment point (MR) per hour or combat round.
This works out to MR x ST x time = PSP cost. Combat rounds cost the same as
Spelljamming hours because on the whole combat requires a lot more
consentration and thought than traveling in straight lines through space.

Because of the large amounts of mental energy involved in both the creation
and use of these helms, many of these helms (50%) become intelligent and
bond with thier users. These helms maintain a constant and unbreakable
mental link with thier helmsman and can follow commands from a distance.
They will also reject anyone other than the currently bonded psionist from
operating the helm. Also, most of these helms (80%) store a PSP pool
(usually 250, but can be up to 500) in the helm, allowing them to assist
the psionist in defensive actions, and recharge at a rate of 1 PSP per
hour.
