Oh I havent played arena in a month now so I dont actually know.
To answer your question, yes. Without aftermath though, it would be slow unless you use some other forms of movement to increase survival. Aftermath though is meant for movement,resetting cooldown, fear and taunt. Cronos made a hachimon build and based on it, you can make meteor be like the throwsword of a hachimon. Since it takes less affixes, you can simply focus on pure dmg and have meteor as your main skill. Meteor can get up to 850% dmg if you have meteor 20 (not including extra 20 because it wastes space for higher dps affixes such as glasscannon, ed%,5k ed, etc etc).
You will need a good way to survive and make sure enemy don't get to you though. It would still take quite a few affixes to make you be able to avoid enemies eventually hitting you after that high dodge %. Ofc arc or cosmic orb are really good skills to snipe enemies but to make it effective like hachimon, you need to spam a skill like sprint for eg.
This could be good with frozen if you have high raw dmg or plagued but it all up to you. Green garden used meteor to get enemies but the meteor was best for poison dmg because its big and 750% dmg helps with the plagued+druidic+high regen+ed% and all combined along with that crater dmg. That is just one example and can still be easily done with throwsword or sprint or something.
Pure meteor build without aftermath is possible but tricky. I know rogues can use perma stealth and a pure meteor along with that high poison dmg from mayhem project build but thats all I can think of. Still think you should go with aftermath and rest op affixes but you will still need to use 1 slot for set, one slot for master mythstone, 2 slot for all sets and 2 slot for 50% meteor proc to guarantee shatter that is spammable, not to mention a replenishable mana source.
Anyway for a pure meteor build without aftermath, one thing any dps build should have or can have (wizards especially should have empower), at least 1 50% glasscannon, 2-3 ed%,nature 30% ed if the 5% ed is on all 6 gears, 225% crit dmg, 45% crit chance, rage to easily max crit dmg out (a rogue talent to add 200% crit over cap), at least 30% deadly strike, 30% dodge as survival and bonus with pathfinder for even higher dmg, 30% crushing blow if your objective is to go high floor indefinitely (really good if it occurs quickly), 100% or more elem crit(blight, blistering etc.), an 30% elemental crit legend affix if need be, if you are a move speed build, momentum, ice should be permafrost with frozen, poison as you know should be druidic, high regen (equivalence is good at that for mp regen) and plagued,
mythic like bombard/cosmic orb/ arc,nova/vanish, ruptured/brutal/exposed,energy/equivalence/discordance if you aim for discordance build like lohko for eg, harmony/ desperation if need be,sanctuary/empyrean and some more things to keep in mind. There are so many things.
Meteor can reach up to billions of dmg if you get it right. Throwsword had high dmg on hachimon build because he got the raw dmg high enough and frozen also multiplies it whenever enemies explode and freezing although he didn't often use throwsword in that video. He often used sprint and that was also his main dmg. There are many great ideas though. You can also tamper with other element such as fire or shock to see if you like it for dmg. Crushing blow is key if you feel like wanting to reach extreme high floors.
Btw in new patch, arena is mostly fire and bleed. Campaign wise has got easier because of new items plus ascensions
