Pan drawers instead of larder with drawers?

[YorkshireTea86]

After looking at built under double ovens and talking to family etc we have decided to go for a double eye level oven. However we can't fit in the larder and oven unit so would putting in some 800 and 600 wide pan drawers replace the larder? Larder would have been 500 wide with 4 drawers. We get 2 pan drawers under the oven too for trays then 800 ones under the hob for pans.
This is sort of the design but doesn't show the pan drawers under the oven.

I've got an eye level double oven with a single deepish pan drawer underneath, and a hob with 800 wide drawers underneath. The under-oven drawer and one of the bob drawers is enough for all my pans and trays, but that doesn't include my casserole dishes.

We've got a 900 l shaped corner unit where I was planning on putting the casserole dishes.
I'm more concerned if 2 800 wide pan drawers and 1 600 wide would give me a similar amount to a larder for thimost like cans, pasta, rice etc. At the minute it's all in a 1000 wall and half a 600 wall unit.
