foot/ankle choice for bilat TT with many issues.

I have been working with a difficult fitting situation for 25 years and
need some advice. The current prostheses provide the best function so
far but still have issues.
40 yr old female, bilat TT at age 15 months, currently at 5 tall,
estimated anatomical height 5' 3, 175 lbs, normal hip and knee
strength and leg length, residual limb tibial length 1.5 and 1.25,
residual limbs very thin, no extra soft tissue, very average
configuration. Tibias are tapered, not normal cross section thickness
due to her age at amputation. Wearing size 210 Otto Bock locking liners.
Currently wearing locking liner sockets, knee joints, laminated thigh
cuffs, back-check straps with knees slightly flexed, (limited
flexion/extension control in first few degrees of motion due to short
limbs), CP Soleus feet; approximate loading 50% on thighs, 50% on
limbs.
Walking for most activities, very determined not to use a wheelchair.
Lives in a basement apartment, no elevator. Married with active 4 yr
old son.
Recently provided CP Sidekick feet assembled as short as possible,
which she likes for most activities outdoors.
Issues; with the Soleus feet she has a very small area of
balance/foundation for standing stability due to the flexibility of the
feet and poor control of flexion/extension. Very minor changes in foot
AP placement or plantar/dorsiflexion result in feelings of instability.
Any change in grade is difficult.
I have thought that she would benefit from microprocessor controlled
feet, with or without hydraulic ankle control. We have decided to make
her shorter to improve her balance but cannot get much with the Soleus
feet. I spend hours adjusting foot alignment when she changes shoes,
gains weight, etc.
Tried to talk her in to flexed knee sockets with C-legs. No go.
So I'm asking for your opinion of what feet would improve balance
standing while improving safety on slopes. Also if anyone has any idea
how to improve control of knee flexion and extension that would be
great.
