1500pt Harlequin List using Formations - 2++ re-rollable Jink?

So just thinking of some lists today and I came up with the following, would be interesting to hear if people thought it was viable:

Faolchù’s Blade - 945pts

6 Skyweavers + Zephrglaive	360
6 Skyweavers + Zephrglaive	360
3 Void Weaver	225

(Re-Roll cover saves while jinking)

Way of Heroes - 310pts

Death Jester	60
Shadow Seer (ML2)	85
Solitaire Cegorach's Rose Haywire	145 15 5

(Infiltrate // Shrouded // Stealth)

Company of Actors - 245pts

5 man Troupe (TM with Caress)	100
Death Jester	60
Shadow Seer (ML2)	85

(Crusader)

Basic idea would be Shadow Seers cast Shrouded/Stealth on the Bikes for 2+ re-rollable jink saves, Heroes all have Shrouded/Stealth already.

Void Weavers for Heavy Armour and Bikes should deal with light armour (36 S6 shots, 42 with the Jesters)

Strong in combat with 30 I think? Ap2 attacks on the charge from each unit of bikes, Death Jester can pull things about a bit as and when that works. 

Just some random thoughts anyway but seems pretty nasty and very aggressive whilst having some durability with the shrouded/stealth giving 24 T4 2++ models and once you're through that, you've got the Solitaire tearing through you and still have Death Jesters, Shadow Seers and a Harlequin Troupe as well as the Void Weaver offering anti horde and.or anti heavy armour
