First have the heals work towards the 50% beacon of light transfer. Second make it so it also works for damage done by Holy Shock. The holy shock change coupled with the Holy Shock glyph would sacrifice a bit of Healing but help contribute to dps.
So with this glyph the alternate playstyle for paladins would be focus on dpsing a boss. Beacon on tank. 30% of damage done healing party members who need healing. Any heals not going to the tank also heal the tank for 15% of your damage done. Couple this with selfless healer for a free insta cast FoL every 18 seconds (more with haste). with the right amount of haste you could make your Holy Light Holy Radiance etc. Insta cast with Holy Shock crits.
The main downside I can see is the lack of a use for mastery with this playstyle.
So gearing priority would be Haste to cap so Holy Shock crits give insta cast heals. Then crit to insure Holy Shock get mostly crits.
Keep beacon of light on tank.
Judgement oncooldown cooldown.
Insta cast FoL on 3 judgements.
Holy Shock on mob.
Holy radiance or Holy light on Holy Shock crits as insta cast.
Word of Glory as needed.
