A 1x12 ain't even close to being strong enough to be safe as a walkboard...
A sound 2x12 would be adequate depending on the weight but will still be
As someone else noted, renting or purchasing a walkboard would be a
reasonable solution. Also, there is a class of lumber that is
ANSI-stamped as "scaffolding-rated" but if OP can even find it locally,
it will probably be as expensive if not more than Al scaffold walkboard.
I wouldnt use a 1x board because dressed thats only 3\\4 of an inch .If
It was me I would
go rent a scaffold board of alum or what they may have. But be sure
and let them know
what u r using it for.
A 2x12 will work fine, not a 1x12. If you want to make an excellent plank, use
the 2x12 and screw a 2x4 or 2x3 under each edge. This is way stiffer than most
aluminum planks. I have a pair made that way that I use when I don't want to
get out my 24' aluminum plank.
Run a rope between the ladders to act as a catch rail, or better yet, clamp a
2x4 between them as long as you can get it high enough so it doesn't become its
own trip hazard.
Be aware that using a plank between step ladders does not provide sideways
stability like ladder jacks would do. Don't push off on the house or the whole
thing can topple if not otherwise restrained.

I'm sure Dennis meant to add this:
Turn the 2x4 on edge for strength. Lying it flat won't add much
stabilty at all.
Just make sure someone is video taping you, if you decide to go this
route. You may be eligible for a $10k prize, on America's Funniest Videos.
I don't know if $10K would cover the hospital bill though.
Scaffolding would be a much safer option, but wouldn't help with your
knee problem. I think it would be very difficult to get good stability
with a plank and stepladders, and on a plank you have to rely on agility
that your knees may no longer have. I do use a 1x12 on an articulated
ladder to work on my boat, but I am not going very high to do that. The
articulated ladder supports the board about every three feet. For a
longer span, I would want a plank (the planks I have seen flex far less
than dimensional lumber, but I suppose adding a strengthening rail to a
2x12 would give good stability, too. The advantage, to me, of a plank
is that the length can be varied to fit the job, or the storage area.
Renting an elevating platform would be your best solution as you could
ride up and down to just where you want to be. I think some can even be
driven along while you are elevated, but I'd rather ride down and check
the footing when you have to move more than the length of the platform.
A cherry picker would also work, but I think their rental is higher.
