So…Some help (eventually 
):
Is that a real question in this world? 
Probably, and start learning to mod/build some lights is a nice way to escape boredom 
That I don’t know, but I do know one thing: you can do it!!
You’ll need to start somewhere, you’ll need the tools, the materials, the skills, but you don’t get it from nothing!
So, at least, order your stuff, start practising and you’ll be able to do it
Or do you think that all the modders around here were born like they are now? :student:
Well, that depends on your decision, your wallet and the shipping companies But, I do hope you already got all the stuff because now you won’t have any excuse that stops you from start modding!! :partying_face:

Here’s some help:
Threads asking for the S11 Quad:
Proper spacer for the quad: Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022)) - #1661 by MascaratumB
The S11 quad is on my horizon! That is a beast of a light!!! Even if it gets hot on a quad, it will eventually hold a little more than the other lights you mentioned (S2+, FW3A). It is bigger, thicker and surely can take some beats too in case you use it as a work / walking light and drop it more!
It is surely an expensive mod, but remember that you’ll have a light that will last you…“forever” if you do it right!
Some specific things:
Driver: If the light takes a larger driver see if MTN has the same firmware in those drivers and avoid using the driver spacer.
Firmware/User Interface: About Crescendo, a while ago I did a video with using a light with that FW. You can see it here: Driver giveaway: Constant current 17mm drivers, winners (finally) announced, post #2. - #150 by MascaratumB See it it suits you or if you prefer another type of user interface!
Soldering skills: They come with practice, with a good soldering iron and a good solder wire too! Start practicing in other things you may have laying around so that you learn before you “really” mod the light you want. I am still looking for the perfect conditions as an amateur modder…

Hey, I am not a good modder, I startd with the same fears you have, and I still have many of them! But I’ll leave you some sort of inspiration:
This is the quad light I made for the Old Lumens Contest 2019. I was also fearing some of the same stuff, but it ended up well and it is now a light that I will keep for life!
You do your quad S11 and you’ll see you won’t regret
Good work and tell us what you’ll do :+1:
