AoS getting back into the game with the new codex and rules need help with 1000 points

i dont play anywhere beside at my friends house so we are lax with the rule but we try to keep everything as lagit as posiable but its mostly for fun

i like the idea of a stegadon heavy list for the laugh so i was thinking
1000 points
Coalesced Thunder Lizard

leader
stegadon with skink cheif
prime warbeast and fusil of conflagration
skystreak bow

battline
stegadon
skystrike bow

stegadon
skystrike bow

and either 2 squads of 20 skins with spitters and bucklers or one squad of 40

again the games are just for fun and not to serious

also though of using a engine of the god as a leader instead

any ideas or help would be great

thanks in advance
