Safe to tune .025 to G?

[Oneirogenic]

So I have been in experimenting with higher tunings for solo and a bit of ensemble work and I've found I'm happy with DGCF, CGCG, and a few open chord tunings. The problem is I want to order a custom DR set and the lightest gauge they offer (that I know of) is a .025 which I'm assuming is their 'F' string and I'm worried that wouldn't tune up to G without risk of breaking. I'm currently using a plain .017 guitar string which doesn't sound satisfactory for me on a fretless. My bass is a Warwick fretless Corvette '34 scale. If anyone can provide any insight on whether a .025 will work or any alternatives I'm all ears. I've thought about lowering the tuning a bit but I'd have an easier time staying in key with my afformentioned tunings. I'm pretty adamant about using DRs too.... Thanks in advance to anyone who has any ideas

You'll be pushing 60 pounds with a .025 - it won't take it.

You ought to be able to go to .019 plain. It sounds to me that you are after a wound string though. Wounds get dodgy under .025. I won't make one thinner than that as they are unstable and fragile.
