Replace Wooden Retaining Wall

Replace Wooden Retaining Wall
The wooden retaining wall (20ft wide x 4ft high) in my front yard is starting to show its age. I'm planning to replace it with the easy to install retaining wall block system. The most difficult part of the project, I think, is dismantling the old wooden wall. Question - Would it be ok if I leave the old wooden wall, as is, and install the retaining wall blocks in front of it and fill the gaps between the old and the new wall with aggregate and soil?
Thanks,
Romy

Yes, you should be fine doing it that way. But make sure the soil used to fill in between walls is packed in all the way and fully filled in. If there is any gap between walls and the back wall fails it could lead to unsafe loading of the new wall.

Do not use ordinary soil for filling between the walls.
Follow the instructions for the retaining wall block and fill with gravel or a granular backfill. Compacted soil containing clay is a guarantee for failure. Most problems with retaining walls have little to do with the wall itself. The backfill containing moisture is the cause of failures and short lives.
