First, here are some "Memorial" links from previous threads on this site:
The Lord's Evening Meal - How Often? Here
A post from a "New Covenant" thread that has similar thoughts as the thread linked above: Here. Also, note the points about the insertion of "it" in the NWT within the context of 1 Cor 11:17-34.
A post from the first link that shows the consistent linking of "eating" and "drinking" the emblems as part of "observing" the Lord's Evening Meal: Here
Meleti has a good write up discussing the calendar problems associated with the WT's yearly Memorial: Here
An excellent post (here) on what "discerning the body" refers to. (1Co 11:27, 29)
The Great Crowd, the Abrahamic Covenant, and the New Covenant: Here.
With those links (and there are many good posts on those links) out of the way, I wanted to post some reference work and see other's views also on the idea of Christians holding to a "Memorial Season." What especially concerns me on this subject is Gal 4:8-12. But there may be other mitigating aspects that I haven't considered. So I was hoping to get the views of others also.
Edited to add: A few more links on the topic of the memorial:
My last memorial talk, which was also my first time partaking: Here.
On the passing of the emblems and Judas: Here.
An article I found on what was in the wine at the Last Supper: Here. The reason I added this here is because the WT insists that the wine for the Memorial has to be without any additives or fortified in any way. Where they get that from is a mystery to me. But the linked article is quite interesting in that regard.
