Your problem is surges. 12 volt wiring sounds good, except how the 12 volts
is down converted is another problem. Any electronics is likely to be
zapped. Resistors are inefficient. I would think you may want to go a room
at a time to see what works in the long run. Separate emergency lights for
each room is another Thought.

Like someone else said, I find it interesting that you say
you have 85 recessed lights in one house. Must be one hell of a
big house. In any case, I would not convert all of them to LED
at once. What's the rush? I'd try converting to LEDs in one
room and try them out. And why do you need an electrician? There
are retrofit kits that fit the common recessed fixtures. Most
of them are just a new light/trim piece with a wire that has a
screw connector that goes into the existing bulb socket.
You can buy them for $25 and put them in yourself. Buy one
and see how you like the light. They come in different color
ranges and you may need to find the color you like.
Theoretically LEDS pay for themselves because they last for
a very long time. But CFLs were sold on that basis too and
the experiences I had with them was that many didn't last
long at all. When LED were $75, they only made sense for
special applications. Now that they are down to $25, they
are worth taking a look. One really nice feature is that
for recessed lights with an attic, cathedral ceiling, etc
above, there are airtight ones available, so there is no
air leakage from the living space. And with a cathedral
ceiling, there is room for insulation around and above
them, so you don't have a square foot of uninsulated ceiling.
