As far as giving Jehovah a good reason to remember to resurrect someone in the New System, I found the following on WT.org:
cl chap. 24 pp. 240-249
Chapter 24
Nothing Can “Separate Us From God’s Love”
The Bible repeatedly connects the resurrection hope with Jehovah ’s memory. The faithful man Job said to Jehovah : “O . . . that you would set a time limit for me and remember me!” (Job 14:13) Jesus referred to the resurrection of “all those in the memorial tombs.” This was appropriate because Jehovah perfectly remembers the dead whom he intends to resurrect.—John 5:28, 29.
AND THIS
- w00 6/1 pp. 14-19
- ‘Save Yourself and Those Who Listen to You’
7 In modern times Jehovah ’s Witnesses have also persevered in the Christian work, even though they have experienced vicious persecution. Has their endurance been in vain? Certainly not, for Jesus assured us: “He that has endured to the end is the one that will be saved,” whether that proves to be the end of the old system or the end of one’s present life. In the resurrection , Jehovah will remember and reward all his faithful servants who have died.—Matthew 24:13; Hebrews 6:10.
Pretty slimy, since neither of those scriptures are specific to the resurrection hope, i.e. more evidence of JWs inserting only loosely-connected passages to support a tenuous stance.
Of course, leaving one's Earthly assets to an apostate/DF/DA beneficiary rather than the WTBTS is likely something that would be frowned upon by Jehovah, and possibly result in his "forgetting" about someone (oops, another continuity slip: how can an omniscient being "forget"?).
But point is, would someone who lived their entire life in hopes of gaining eternal life in the New System (petting lions, etc) suddenly turn over a new leaf near death, and not use it as an opportunity to grease YHWH's palm to gain admission, running up the score just to make sure you're not forgotten?
Highly unlikely....
