List Advice - 2000 Points against Blood Angels (Rage-Cursed Onslaught)

Hi everyone! I hope you're having a great day.

I have a 2000 point game against Blood Angels tomorrow. I haven't played against them before, or even Space Marines generally in a while. I have put together a list and was hoping for some advice: https://www.newrecruit.eu/app/list/fdhgK

The game is casual (just wanting to have some fun) but don't want to stomp my opponent or be stomped. Plan is to screen out as much as I can with the kommandos (splitting the unit with ranged weapons up), using the gretchin to sit on home/midfield objectives and to help screen deepstrikers, and just try and outrange where possible. Plan is for the Hordeboss to go with the Tankbustas in the trukk, and for the Big Mek in MA to join the Flash Gitz in the battlewagon, just for some survivability so they don't get shot off the board turn 1.

Any advice would be appreciated, thank you!!!!

P.S. Did consider a brick of 20 boyz with Ghazghkull and a Painboy because as far as I am aware, the unit can be given Stealth via the detachment ability but thought it may be a bit oppressive for a casual game.
