Well the good news is in Summer, Mt Anne can be done as a day walk, so you are "close" to your vehicle if you have to bail.
Boulder hopping is the first issue I see as an issue that might stop you - there are a number of large boulder screes you will need to cross. The boulders are very large and crevices may exist between them - not super-deep like the K2 movies & the like, but deep enough that if the top is blown over with snow, you may fall into a gap deep enough to sprain your ankle, or worse.
High camp hut is the only real shelter you will get up there (apart from the outhouse, which I wouldn't recommend). There are limited tent sites there too.
Your only other option as I see it is Shelf Camp.
Shelf camp is very exposed, and you have probably already read it has a reputation for blowing tents away.
Weather in late June??
Cold, windy, icy, snowy, all of the above?
Snow shoes? The snow cover would have to be pretty significant on those boulder fields for SS's to be of benefit as the boulders are so large - to cross over the top of them with snow shoes, you would need metres of snow, which is unlikely unless we get a big dump - in which case you wouldn't want to go anywhere near the place.
You really need to dig out as many photos of the ascent as you can find and imagine them being covered in snow and ice, to detirmine for yourself whether ice axe and crampons would be of benefit for you. Or indeed snow shoes as I have never used them so don't go by what I say.
I myself would not attempt this ascent in winter.
I'm not saying it cannot be done, because I don't know. But having seen it all covered in snow in summer (Feb this year), I wouldn't even try.

A mobile phone on the NextG network would be of assistance - good coverage from Shelf Camp when I was there.
When I was there in Feb and the front came across while we were camped at Shelf Camp, with the wind and snow, I had an evacuation plan in mind, something along the lines of:
If things turned dire (tent ripped / can't get dry; tent blown away; some other unforseeable event that meant chances of survival reduced if we stayed there), we would get dressed into as much clothing as we could put on, get the head torches on, compass & whistle around neck, keep the spare batteries at the ready along with all the readily edible high energy food we could muster (dried fruit, chocolate etc), water easily accessable, full wet weather gear on inc. beanie or balaclava and snow gloves, GPS at hand with waypoints already set from the journey in, pack our gear as quickly as we could but try to keep the sleeping bags dry, hydrate (have a good drink before setting off), and head for Shelf Camp hut in a slow & steady & sure-of-foot manner. At the hut we would decide, based on how we felt, whether to get into our sleeping bags for some warmth and rest, or proceed to the car, the food stash, the welcoming heater, and guaranteed survival.
Sounds extreme, but having experienced a demolished tent in the middle of one night on an exposed ridge in southern Tassie some 16 years ago, it doesn't hurt to at least consider your options if a situation eventuated. The weather sure can turn it on!!
