Revered Return challenge is unreasonably long to grind on SSF compared to other challenges

Revered Return challenge requires to complete 4 of 5 listed challenges:

5 Orbs of Rememberance
5 Orbs of Unravelling
10 Orbs of Intention
Consume 25000 Petals
Consume 2000 Memory Strands on Equipment

Currently I stand at 37/40 challenges done including:

Maniacal Magnitudes (52418/60000)
Revered Return (2/4 - 25000 Petals and 2000 Memory Strands)
Strenuous Summons (209/250)

I have included memory thread points in every Atlas Skill tree I have used since it was possible. As it stands I have completed about 5 of each of the new boss (around 15 memory threads) + quest versions and I have only 4 Orbs of Intention.

I have 6,5 days played on my current main not counting some time played on a different char at the start of the league on which I have done the quest version of each of the new boss.

This may be countered by saying "challenges are balanced around trade", but this is the first time since I remember that unique maps challenge was changed to complete 40 unique maps instead of fishing for Doryani's Machinarium in Delve/Comprehensive Reports, which to me was the notorious "RNG" challenge for SSF in the past, so it seems like it was the intention that there is less of these heavy RNG challenges.

At the moment the only option I see is create a mule with currency/few items and migrate it to trade to complete this challenge, because extrapolating from my current play time and my current orbs, assuming I would drop any of the Rememberance/Intention orbs at the relative speed of Orbs of Intention it would take around 2 more weeks at the very least of pure playtime to complete this challenge. This is again after doing 4 Pinnacles, 30 T17, Level 100, and almost finishing Maniacal Magnitudes which is the "grind challenge" this league.

While not a bug technically, this feels very bad, much worse than looking for Doryani's Machinarium did, because Machinarium would need to be found only once, while 2 out of 3 of these orbs did not drop at all for me and 1 is not even half required after 15+ memory threads for which I specced each Atlas and mostly fully cleared map layouts where I would not miss them.

Challenge would feel much better if use of orbs would only require one of each and/or only requiring 3/5 and not 4/5. In that case atlas could be targeted at specific bosses, so one could run a boss until they found an orb from that boss and then focus on other ones. In that case I believe dropping Unravelling/Rememberance would be doable after more tries in the same timespan and would be much less prone to bad RNG.
