Should I drill more holes in my false bottom?

Attached is the mash tun I just made using a tamale steamer. I plan to place my BIAB bag inside of the tun for a sort of hybrid tun/Biab setup. I intend to fly sparge.
Should I drill some more holes in my false bottom? Let me know yer opinions.
Thanks!

For a BIAB setup, I wouldn't bother, that will work just fine. For an all-grain setup, those holes are too big, you'd need a lightweight screen with much smaller holes to sit on top of that one.
