Dark Eldar Shining Spears!

These days I'm running two formations of Ynnead's Net (basically eight bike-units from all three factions). For bike-fluffy, I'd like to make a unit of shining spears but they use the old CWE bikes that I don't like so much.

Alternatively, I'm considering using my remnant reavers. I bought too many so at least three won't be used anyway for a long time. My plan is to repaint the bikes following my craftworld colors while remaining the riders from my kabal colors, implying the alliance under Ynnead.

The issue is the lance, however. The spears in the DE vehicle boxes don't look cool for me. The greynight's spear has good design, but it's not like a lance on the horsebike. Any alternatives either for GW/FW or third parties? Or good references? Your suggestions will be much appreciated!

Personally, I utterly love the look of a Dire Avenger Power Glaive with the top bit replaced with a Dark Lance barrel:



I'm sure you could find suitable DEldar arms to pull the same trick. Perhaps that one from the Raider kit that's holding a boarding hook, and the Power Spear from the Scourge kit.

Wow it's pretty awesome. I should find my bitsbox for remnant dark lances (not sure of that though, cause I may have already used as many bits as possible for the cool design)

I'd rock something like this:

Edit: Just look at the sprues
