Suitable spears/lances for an Inceptor conversion

[Knightsword]

Title says it all really. I'm looking at converting some inceptors into power lance armed jump pack knights. Does anyone have any recommendations of suitable lances from other armies to use for this? I've trawled through a few bits stores already but I can't get a good of scale from the product photos.

Kromlech do a good set of Power Glaives which work nicely in Space Marine hands. Otherwise Grey Knight or Adeptus Custodes halberds with maybe an end swap for a broad headed spear (Glade guard or similar)

Or a power sword blade

AoS Stormcast Prosecutors with Javelins?

Oh wow the stormcast glaives are so damn long! Thanks for the ideas. I'll probably look at using either the Grey Knight halberds or the Stormcast Protector glaives.

The upcoming custodes jetbikes are also armed with power lances, they might be an option to consider.

I've just seen them. They would look amazing for this project. I'm very very torn between waiting for those to come out or getting the stormcast parts. It doesn't help my impatience that the Inceptors arrived this morning...

Grey Knight terminator halberds would give you more one handed weapons, but the Stormcast glaives have nicer shaft detail in my opinion.

I've ended up going with the Grey Knight halberds for the Inceptor conversions (which arrived today actually). However when I get round to doing the biker versions I'm going to use the Custodian lances. I feel those will be better suited length-wise for bikers and also have more of a jousting lance aesthetic than the Stormcast glaives do.
