Lightning arrow + Javelin of Lightning?

[Climbover73]

A character using a javelin of lightning that speaks its command word then uses their bonus action to cast the lightning arrow spell on/with that same javelin before hurling it? Will the two effects stack this way for combined damage dice? (4d6 lightning + 3rd level casting 4d8/2d8 lightning arrow)

I've no doubt this has been asked before. I lean toward this probably being a no, but only because it seems to sweet to be true.

The only thing I see making it a possible no is that in the lightning arrow spell description, it says; "The target takes 4d8 lightning damage on a hit, or half as much on a miss, instead of the weapons normal damage"

However, I would think the weapons "normal damage" is the 1d6 physical damage of the javelin since the javelin of lightning description says; "On a hit, the target takes damage from the javelin, plus 4d6 lightning damage". So is the lightning damage gained from speaking the weapons command word considered part of the weapons "normal damage"? I would definitely say the 1d6 physical is lost due to lightning arrows spell description, just not sure about the 4d6 lightning gained from speaking the command word.

There's no "hit" when you use the javelin to turn it into lightning, as the effect is save-based, no attack roll is involved.

In the description of javelin of lightning it states that the target of your javelin takes 4d6 lightning damage, plus the javelins damage, on a hit. I'm not speaking of the dex save damage only.
