No, it would not do. Even aside from the fact that the ports are
facing in a direction that would interfere with the base unit, it
lacks a air control valve for the booster.
A quick summary is in order:
The design of the P6, with its very low mounted master cylinders,
required the use of a remote, hydraulic booster, unlike a more normal
design that adds a vacuum booster to the master cylinder itself. So
the P6 design is complicated, having in essence two complete "master
cylinders", one powered by our foot, the other powered by air at the
behest of our foot. This is for the single circuit system. It is also
more complex from the operational standpoint, as an extra hydraulic
circuit is needed to control the booster (unlike the more normal
system, where the booster is controlled mechanically by foot
pressure). This is the cause of much grief.
The tandem systems required twice as many components, though the foot
master cylinders are combined in one casting.
This was all fine and dandy for the 4cyl cars , but trouble arose
with the V8. Not enough room! So they made the system even more
complex, by shifting the hydraulic circuit that controlled the
booster from the booster cylinder to the foot master, thereby placing
this problematic bit to an even more challenging location in the car,
low and beside the exhaust manifold of the engine.
New parts, rather than rebuilds, would pretty much rid the cars of
problems, but new parts are all but impossible to find now.
