I appricate the thought Myriad, but as it happen internal ware isn't a huge issue, sure you can overdrive it, but as it requires surgery to repair, so the usefulness is strictly limited.
The redundancy complex form works wonders here 
Yeah, I looked at that one too. Im just not sure what would take damage first. As normally you would check the damage boxes from left to right, and any increase in the condition monitor would be added at the end to the right.
Say your ware has 9 matrix condition boxes, gains 3 extra from redundancy - it now has 12 boxes. Then overdrive is halted and the cyberware suffers 3 damage.
It now has 3 damage and 12 matrix boxes in total (9 of which are unchecked).
Now you drop redundancy- you now have 3 boxes of damage still, and 9 boxes in total ( 6 unchecked).
What you could do though:
1) convince your gaming table that everyone should make a matrix focused character.
2)Make a device modification (data trails) to add a persona firmware to your internal cyberware.
3) convince one of your buddies to make a technoshaman
4) when your cyberware needs to be prepared create your persona on said ware and have the technoshamans great firm companion sprite use its sacrifice power on your (damaged) persona
5) profit
Regarding cyberlimbs and modules. Could you add the "induction receiver" module to your limb and have a toned down version of the skinlink echo?
