In other words, the odds are that the speaker will speak from a pre-printed outline and use his death and funeral as an agenda to promote the Watchtower Printing Corporation and its religious interests.
Doug, LDH suggestion is very good, also it's worth a try to prepare and present a general outline much like you wrote.
I wrote much the same for my father and my active brother submitted the outline for approval. The material was used within the standard JW outline and I felt the elder did a credible job with it. However, this PO had a heart, your dads PO may not.
There were some surprised faces at the Kingdom Hall when the congregation discovered that one of the most frugally dressed, unassuming brothers anywhere, had a WWII military record that made the Rangers of ‘Saving Private Ryan’ look like a Boy Scout troop.
Unfortunately you may have to work within the ‘comfort’ parameters of the presiding elder.
But I feel if the compromise is palpable, it’s well worth it so that as many people recognize the contributions your father has made for his family and community, Jehovah’s Witnesses or otherwise.
