New Exterior Panel help with fastening

[Elutte]

Hi. Planning to replace the exterior panel. My idea is to keep the old one, then nail 45x45 studs vertically, then add 45 insulation, followed by a wind barrier. Then battens 12x48 on top of the wind barrier on the 45 studs, followed by horizontal panel 22x95 double pitch.

But I've encountered a problem now that I'm about to start with the studs. I planned for a 60cc spacing, but I see the old ones are nailed with about 80-90cc. So the new stud at 60cc will only be nailed to the old boards, which means they will only be nailed to the corners and around the windows, etc., not to the old studs???

What would you do???

The current setup is like this: a timber panel on the inside, then a stone wool board with insulation, then the exterior panel. So I have 90mm nails and they don’t reach the timber panel...

I had removed the old panel, it's better in every way: You can add more studs if you need for a new panel, the wall doesn't protrude as much, nicer around windows which don't become as deep in the wall, etc.

I would have removed the old panel, it's better in every way: pthen you can add more studs if needed for the new panel, the wall doesn't extend out as much, neater at windows that won't be as deep in the wall, etc.

removing the old panel is not an option. unfortunately

I mostly wonder if I can continue nailing at 60cc? Will the new panel stay in place when all the new panel is up? I'm nailing with a lot of nails and have tried leveraging with a crowbar on the new stud and it seems to hold tight.

Why not lay the studs horizontally?
I also agree with the previous comment, the old panel should be removed!! If you get air movements around the old panel, you've insulated in vain.
You don't put new tiles over the old ones in the bathroom just because you don't feel like tearing down the old ones, do you?
