I may not have a crystal clear understanding of your situation, but why are you delivering ESIGN's preconsent disclosures at account opening when you plan (for now) to provide all of the "written" product disclosures in paper form? Granted, Section 7001(c)(1)(A) of ESIGN says you must deliver your "how our e-delivery system works" disclosures prior to obtaining the consumer's consent...but this section doesn't say how far in advance is too far. Although there's no direct connection, it seems that Reg. E's "close proximity" timing standard should be equally appropriate when judging the timeliness of ESIGN's preconsent disclosures.
The breadth of consent (ranging from a single document to a category of documents and list of accounts) is up to you...but you have to spell it out in advance. Unless future e-delivery service is exactly like the existing service, you're taking an unnecessary risk. I'd put the customer through another demonstrable consent exercise so you have proof that s/he has the necessary hardware, software, and savvy to successfully receive, open, and read any e-documents that will be delivered by a variant of the previously consented method(s).
