About Former Bonus Reward (Patreon)

I'm planning to put the previous bonus rewards on the Patreon Shop, so that friends who missed them earlier can purchase them more easily. The planned price is $7.50 per comic. My bonus rewards started in August 2021, so I'm thinking of making some of the earlier ones available for free on Pixiv and here—perhaps selecting 5 or 6 of them to release for free, while putting the rest on the shop. This way, I can both offer some content for free to everyone and use it as a way to promote the rest. What do you all think of this idea?

我计划将之前的额外奖励上架patroen商店，方便之前错过的朋友们购买，计划的定价是7.5美元一部，我的额外奖励开始于2021年8月，所以我在想是不是可以把一些早期的额外奖励在pixiv和这里免费放出，比如选择之前的5-6部免费放出，其他的上架商店，一方面给大家免费放一部分，一方面也能帮我起到宣传的效果，大家的意见如何？
