Idly looking through the RS catalogue I found film capacitors with some pretty impressive specs. Cheaper suppliers may well be available.
4.7uF, 275VAC, 600VDC £8.71+VAT

Motor run caps such as: https://uk.rs-online.com/web/p/polypropy...s/3888049/
30uF 450VAC £12.50+VAT 92mm x 40mm
That's a lot of capacitor for your money.
500uF 350VAC £51+VAT
https://uk.rs-online.com/web/p/polypropy...s/1729045/
It may be over 9" long and 3" diameter but that's a stonking amount of heavy duty capacitance.
4 of these in series/parallel will replace a 0.1uF 5kV smoother in a TV with mains EHT. £6.80+VAT each
https://uk.rs-online.com/web/p/polypropy...s/3847795/
If you have £300 to spare you can have 3000uF 800VDC. Three thousand microfarads! 340mm x 116mm so it's not exactly petite.
