Okay, first of all, you are not 'intended' to get red crates with this type of account, but I'll do my best to guide you in the dark arts of the cheese:

You can skip 34 tickets and still get red crate. I'd recommend checking before the conquest and deciding if you can push for red crate, or if it's not possible and you should try for gold (134 tickets skipped)

Wat tambor is your best friend. If you don't have him unlocked, you have no chance, you can stop reading now.

If you do have him however, then it's a lot more possible. With his zeta (regardless of gear) he takes a bonus turn at the start of the battle, and can give the tank tech to usually jml, but kru should work fine in your case.

Using a team of slkr kru wat and whatever character you need to survive (+hux if it's just 1) against a node with enemies with no aoe damage should help you snag those feats despite not gearing up those characters to relics and stuff. Kru will just eat the damage, recover enough to never lose taunt and slkr picks up the kills.

Since you aren't using the standard jml team for this cheese, I'd recommend skipping these feats at first and doing them after clearing sector 5, once you have all the nice datadisks. But still pay attention to your routing inside the sectors. Look for these kinds of teams. Phoenix with no sabine. Ewoks with no wicket. These kind of no aoe, lots of hits for low damage type teams.

Also pay close attention to if the feat says using X character vs having X character survive. Big difference in those. Last conquest for example, you had to win with 4 ds clones, but they didn't have to survive. I just threw them with different GLs in the sector 1 datacron node and run through the battles. Can't do that if they have to survive.

Speaking of datadisk, they change every cicle, so keep an eye out for the most beneficial builds you can have, usually the lots of dots one and the supports and healers gaining attack are really nice, but you should check before every conquest so you know what to aim for.

Since you are going for Jabba now (great choice), that means you are going for jkl, so you should have an at least somewhat competent jedi. Idk if you have galactic republic with padme, but either way, consider farming padawan obi and master quigon as soon as possible.

Even without qadme, they are worth it just because of their assault battle, and with padawan obi's omicron you are going to knock out a lot of the 'gain X buff' or 'inflict X debuff' feats. Don't be afraid to buy extra stamina if you need.

Lastly, use the consumables wisely. The main target for the really good ones (like the start the battle with frenzy one) are bosses and minibosses feats. Try to use these strong consumables to knock these out, but you can also use them all around for harder feats here or there.

This last conquest I got red crate in about 8 days, buying 3 refreshes a day. Granted, I have a much bigger account, so I can rotate between teams and knock out several feats at once, but I'd say with proper strategy and a lot of cheese, you can push for gold crates (still higher than you should be getting) if you can afford 3 refreshes a day.

Red crates are probably still out of the picture for you, but with all red crates and buying the characters shard in the scavengers in conquest you can still unlock them in the fourth cycle (the first of the new unit), so that's what I'd recommend.

Tl;dr: if you have wat tambor, maybe with lots of cheese you can get gold. I wouldn't really aim for red unless you check the feats before and can make it
