Thats a good timeline if you want to take things slow. Depending on your fitness and skills, some can still make it a one day trip but you would have to start very early (make it to LBSL at sunrise).
But if your fit, got some skills under you as well as the equipment, then I don't see why you can't start early Friday as your planning and camp out at UBSL or Iceberg then summit on Saturday and come back to the portal.
I went up a about two weeks ago and had to start using crampons just after the boulder field right above LBSL. The talus was all ice. From that point to Iceberg lake I was taking my spikes off a lot because there were a lot of sections where they were not necessary. Probably not the case because there was a recent storm. Maybe snowshoes would be a good idea to bring in case but hopefully a majority of the route is fairly packed enough to get by with crampons.
Good Luck!
