How would you guys gear 2 jobs with the same role?

Trying to gear both drg and smn

In 2.0 i always gear dps/heal, dps/tank or heal/tank so in a way they never fight for gear

The same way you gear one only do it twice. Could also just buy or craft the gear...maybe I don't understand the question? o.O

With drg and smn they won't be using any of the same gear. Drg is focused on strength whereas summoner is focused on intelligence to maximize damage outputs. They won't share the same armor or even accessories unless the accessory is vitality and acc/det/crit. Sorry if you were looking for something else, hope you find your solution

yeah, i just realized that. i supposed this was a dumb question lol

Well missions give you two different types of gear: melee and range. Dragoon is melee and Summoner is range. So you can easily maintain both gear sets by doing all side quests and the main quests and have the 145 you'll need for your level 60 dungeons. From there 160 gear drops so frequently that it shouldn't be a problem to get both to 160 while playing only one of them. From there you'll need to make a decision though and granted you will need to play both enough to get to at least level 60.

I actually did this for my tank and mage gear which effectively provides leveling gear for 5 jobs.

I would not worry about crafting/buying gear while leveling assuming you have 130 gear since you'd technically need to level to be self sufficient while crafting that gear. I don't believe you need it for the last story dungeon which doesn't give you any gear but does give you the Law that you can use to get the 145 you'll need to unlock the expert roulette. I did not pay close attention to early IL requirements though.
