Wedding Dress Deconstruction

Hi everyone! Sorry for the long post. I just need some advice.

I bought my dress a few months back. I got it at Ollie's Bargain Outlet when they had a huge promotion selling Demetrios Wedding Dresses. I bought it because it was my favorite of the limited samples and it was inexpensive compared to the ones I loved at bridal stores. I was also swayed by the fact that it kind of resembled my dream dress, the Lazaro 3059. The one thing I didn't love was the silver embroidery. I thought the dress was just dirty, but after I bought it and took it to be dry cleaned, I realized that's just how the embroidery looked. It was fine on the parts of the dress where beads were sewn on top, but by itself I hated it. Also the more I looked at it and tried it on (it's In my closet), the more I regretted buying a knockoff Lazaro and not going with one of the dresses I tried on at David's Bridal that already fit perfectly with no alterations. (There was a Vera Wang on sale, ballgown and gorgeous that I stood in for like 40 minutes and I didnt get it.) So just recently I had the brilliant idea to design a dress with my wedding dress as the base. My dress is a heavy satin base with two layers of tulle over it, the last layer where all the embroidery and beads are sewn on. I was thinking that I could take off all the tulle layers myself and can take the base layer to a seamstress to get it fitted (that part I definitely can't do), and then hand sew appliques onto my dress, possibly a little sleeve, using the beads from the top layer, and buying a tulle overskirt. I'd be completely changing the design but because it wasn't too expensive, I feel like I can deconstruct this dress without feeling bad. I have had experience with sewing and definitely can do it (besides the tailoring part), and surely if I'm taking away the beaded/embroidered part, it will be way cheaper for a seamstress to fit the dress to me because she doesn't have to deal with all the beads. And then I get a little DIY action as well. Plus it will be exactly how I want it, which was more along the style of the Vera Wang, and everything I thought I wanted before I saw the Lazaro and bought the Lazaro-reminicent that is sitting in my closet. It shouldn't be to expensive either, I've already looked at the applique and overskirt I want and it's within my budget.

TLDR, I really want to deconstruct my own wedding dress but am scared and need people to tell me it's a good idea lol.

(And I suppose if you think it's a bad idea, let me know too! If I dont do this, I'll just take the dress in to get fitted and most likely add some sleeves and be done with it.)

Please tell me what you think!
