Old wood cookstove - using the coal grate while burning wood?

[rf2]

I have an old Findlay Meteor wood cookstove at my cottage. It came with both a wood grate and what I believe is a coal grate (never used). I've been using the wood grate to burn wood, and it is working well, but I noticed that if I install the coal grate, it adds at least a few inches to the depth of the firebox. This would be very useful since the firebox is very small when using the wood grate, which means that the fire burns out overnight if I don't get up to add wood a couple of times.
Does anyone know if it's a bad idea to use the coal grate to burn wood? The only disadvantage that I can see right now is that I might loose a bit of control over the air supply, since the adjustment for the coal grate is not as fine as the one for the wood grate.

I can't see it being a huge issue? The only thing I suggest is to try it and see for yourself. Keep in mind, those old cook stoves were never meant to heat an entire home.
