Summoner's Rift Passive Gold Increase

I'm an ARAM player and, one thing that turns me off from playing Summoner's Rift is how slow the passive gold accumulation is in it. In ARAM, when/if you die, you typically have earned some gold and can buy something. In Summoner's Rift, you have to grind or farm in order to assure you'll be able to buy something. That feels like work, not like gaming. Maybe setting the passive gold accumulation to that of ARAM standards would make SR matches faster and more action-packed? If setting it to ARAM standard is too much, can it still be increased some? Thanks.
