Deepstone Sentinel and Dwarven Defender

[EpicEvokerElf]

I'm playing in a fairly high-powered campaign (we're porting over splatbooks on a case-by-case basis), and I'm looking to combine the Dwarven Defender and Deepstone Sentinel (ToB) into a single 10-level prestige class. I'd like to preserve the following from each:

Deepstone Sentinel fancy-schmancy magic powers (Mountain Fortress Stance et. al)
Maneuver access (Stone Dragon, and possibly Iron Heart)
Full BAB
d12 HD
Dodge bonus and DR from DD
Some form of Defensive Stance, adjusted to allow 5ft steps like Stone Dragon stances, possibly as a bonus stance or integrated into the Deepstone Sentinel's Mountain Fortress Stance
Some sort of CON-to-AC ability - new

Entry Reqs would be something along these lines:
Dwarf
Lawful alignment
BAB +7 or +5
Proficient with heavy armor?
Stone Power
Toughness
Dodge?
2 Stone Dragon maneuvers and 1 Stone Dragon Stance
Something else?

What do you think of this concept? Would it be feasible and able to be balanced? Balance concerns are in comparison to higher-power classes; casters, rogues, etc. It's still essentially a wall (5' mobility only, heavy armor), but it's a darn strong one.

Thanks!

You could easily add your stances as talent options to the Bulwark (which is based on the dwarven defender of 3.5).

I know, but it seems a little bland. I'd rather keep the flavor of DD and the Stone Dragon stuff. Essentially I'd be customizing the Bulwark to be identical to this anyway, and I'd have to put level restrictions on some abilities...
