Custom Diaper Bag

I found a really pretty bag on Etsy today, but of course, I can't leave things the way they are.  I'm trying to see if I can have the bag (pictured below) modified.  I want a grey linen to replace the camo.  The lady that makes the bags told me that she was also out of the floral print.  So... I made my own (pictured to the left).  Not really sure how this will turn out, but I'm hoping to end up with a bag that I can use as a purse later!

We are getting a neutral backpack diaper bag for the bf so he won't look like he's holding his wife's purse when he's out with our son.  :)
