Will this be an issue merging charge pipes like this?

Thanks for posting i know there are plenty of people running the "Y" and you were one of the first i thought of however my concern is most have them further down stream of the comp outlets Y'ing close to the TB.
I was worried about having the merge right off the comp outlets possibly blowing air into the other turbo but maybe i'm just trippin lol!
Yes you are correct the plan is to run the car on 100% alcohol after the bugs are worked out on E85

That'll work just fine. I don't think a wider radius transition would make a difference for a race build. Might have weird effects on the street but that would be a guess.
Keep in mind, high pressure (boost) always moves towards low pressure (throttle, bov, wastegate.... or boost leak).

What harm would there to sandwich an a2w intercooler between the base and lid of that Holley intake even if you are running pure alcohol? Wouldn't cooler intake temperatures still be beneficial?
As for the merge,you should be fine. Like mentioned earlier, the boost isn't going to "want" to fight its way into the other turbo, it will gladly take the path of least resistance, towards the intake.

If he's running methanol then the fuel will be colder than an a2w ice bath. Only thing to draw more heat would be to run an a2a core packed with dry ice. However, if IAT is too low the alcohol won't burn right.
It would help to add injectors higher in the runners to allow more cooling effect before the intake ports. Similar effect as nitrous plate vs direct port.

Again thanks for the input you guys!
I'm really trying to keep this race car as simple as possible to ease the maintenance etc as i don't have a dedicated team with me at the track each time out while also trying my best to keep it as safe as possible so after crunching numbers for funds i decided to run straight alcohol.
If any of you saw my build thread (which needs a major update lol) i actually had the 417 Motorsports IC but sold it so that i don't have to run another water tank, lines, etc front to back to hopefully again keep things simple&safe!
Mine is still a budget limited build as i'm not trying to set records or push the set-up to it's max but i like the cost, cooling effect, and tuning window of alcohol and since i had good experiences with Ethanol fuels on my Evo pushing 40psi of boost i figured it'd be a good chance to try and learn something new going 100% alcohol but will likely start out on 160# inj and pump E85 and then throw in larger injs and alcohol and turn up the boost that's why i'm running such a big belt driven FP so i can grow w/o changing too much stuff up....
